Hi, I have a module (naxsi) that reads the body during the REWRITE phase, in the exact same way that ngx_form_input does : https://github.com/calio/form-input-nginx-module.
When used with auth_request (or maybe other modules, but that's the first time I encounter this issue within a few years of usage), there is no request made to the upstream if the request is made using POST/PUT and the body is bigger than client_body_buffer_size. For the simplicity of the example, we'll assume I'm talking about ngx_form_input (behaviour is the same, except code is way shorter). The user reporting me the bug opened a ticket : https://trac.nginx.org/nginx/ticket/801. It is possible to replace naxsi with ngx_for_input and obtain the same results. From Maxim's reply, it seems I failed to properly restore request handlers after reading body. What would be (if there is any) the proper way to read body within REWRITE phase ? Is there any example/existing module that does such so I can understand what am I doing wrong ? (In the past, I always thought ngx_form_input was the reference one). PS: You can find a bit more details here : https://github.com/nbs-system/naxsi/issues/226 (including sample config & commands to reproduce bug) Thanks, -- Thibault Koechlin
